16:9 letterbox to 2.35:1, or leave the Panmorph lens in front of the lens all the time and adjust
the aspect raito per source type.
CLEANING
In most applications lenses do not need very much cleaning
– a bit of dust will not impact image
clarity. However, in today’s high performance home cinemas with very dark rooms a small
build-up of dust or other foreign matter on your projector lens or your Panamorph lens can
produce a measurable reduction in contrast. The most effective cleaning approach is to simply
blow off any dust. If there is any residue or build-up then it is recommended that you clean the
optics with professional lens cleaning supplies such as from a camera store while the lens is in
front of the lit beam of the projector. This will allow you to quickly see both the results of
cleaning and also if you are causing any damage.
